Barrymore's hair was previously a darker mix of brunette and blonde tones.

In the past few years, Drew Barrymore's brownish blonde hair color has been somewhat a signature of hers. Though she's switched it up length-wise (like when she chopped her hair into a bob as a message to her haters), the 43-year-old actress has largely stayed within the bronde realm. However, not anymore.

The "Santa Clarita Diet" star's bronde days are over, judging from the gorgeous, buttery blonde hair color she's been rocking recently. Barrymore's new hair color made its red carpet debut on Monday when she attended a conversation with "Santa Clarita Diet" co-stars Timothy Olymphant and Skyler Gisondo at the Kaufman Concert Hall in New York City.

On the carpet, Barrymore flaunted her just-dyed blonde hair, which she kept darker and golden up top and transitioned to a brighter platinum color toward the bottom. The actress wore her hair in loose, tousled curls, which cascaded down her shoulders. She paired the look with a blue pinstripe suit, which highlighted her lighter blonde.

Judging from Barrymore's Instagram, it's unclear if she's been secretly rocking this buttery blonde hair color for weeks or if she just dyed it a few days ago. (She isn't exactly a pro at taking clear hair selfies.) Either way, it's definitely a somewhat recent hair change considering that she wore her signature blonde hair color on a red carpet just last month at another event.
